TITLE: The problem of protection against electrons and bremsstrahlung from the outer radiation belt of the Earth SOURCE: Moscow. Inzh.-fiz. institut. Voprosy* doximetril I zashchity* ot izIucheniy (Problems of dosimetry and radiation protection), no. 2, 1963, 100-108 TOPIC TAGS:. radiation belt, cosmi.c radiation, radiation protection, beta ray, bremsstrahlung, space flight, electron stream ABSTRACT; The aufhors note't~at in .recent times information on full electron streams and spectrum in the Ehrth's outer radiation belt has undergone considerable modification. It has been found that previous estimates of the full electron streams in the outer radiation belt, based on radiation-counter tests, were ap- proximately 1,000 times too high. The purpose of the present article Is to re- view problems of protection against the electrons and bremsstrahlung of' the outer radiation belt in the light of the new information available with respect to the streams and the spectrum of the electrons. The authors consider the radiation hazard to the astronaut (and, concomitantly, the shielding requirements of the capsule) in terms of the now dati and analyze the contribution of the olectrons Card 1/3 ACCESSION NR: AT4021257 and the bremsstrahlung, respectively, to the over-all dose past the shielding. A model is proposed for this purpose, based on several simplifying assumptions (an isotropic spherical source of bremsstrahlung), and an equation is written for the Intensity of the dose in the center of the cabin. Tables are given, showing the relative contributions of various spectral components of the bremsstrahlun '9 and other parameters as well. it is established that the greatest contributions to the dose intensity of outer belt electron bremisstrahlung are made by electrons with energies of 0.05-0.3 Mev. The data presented refer to a space-capsule wall constructed of a material with thickness d - 0.1-10 9/cmz and atomic number Z (in the particular case of carbon Z = 6, but the data may easily be extrapolated to other light substances by multiplying the values given by Zeff/6). in the pecond section of the article, the estimates derived for the bremsstrahlung doses are supplemented by a calculation of the doses of penetrAting electrons of the outer belt. The author establishes the fact that the intensity of the electron dose decays very rapidly as the thickness of the shielding increases. With a shielding thickness of d < 1.0 9/cm2l by far the greatest part of the dose I due to olectrons which7panetrate through the shielding; at d > I - 2 g/cm the dose is determ1nod entiroly by bromistrahlung. In conclusion, the luthoro offer certain practical considerations with respect to radiation protection In the outer belt, emphasizing two fundamental -requirements: 1) for reduced bremsstrahlung genera- tign, the shielding must be manufactured of a material with-a low atomic number; Card 2/3 ACCESSION NAI AT4021251 ZY for increased bremsstrahlung absorption, the shielding must be manufactured of a material with a high atomic number. The authors note that these conditions are satisfied by a combined shielding, consisting, for example, of a layer of low-Z material (outer layer) and a layer of-high-Z material (inner layer)* Orige art* has: 7 formulas and 7 tables* ASSOCIATION: INZH.-FIZ, INSTITUT, MOSCOW (Engineering Physics Institute) SUBMITTED: 00 DATE ACQ. 06Apr64 ENCL 00 SUB CODE: 5V, LS NO REF SOV; 009 0 -RER: 903 Card 3/3 (t) 5 1)~EWP(q)/K,.ri(m)/rCC(Cw)/FDS~v)-2P..CS/BDS/M(a)/I~i(j)/~jc)/ _2N(v 4 ES~hk /t (/qp)o-~EpSe /L/E AAIMCA/AFFTC ASD AFMDC/ESD-3/APGC/SSD Pb- 0;~V RD J~DD Pi )P ~h h/ -h/Pq-h A R/ ACCESSION NR: 'AT3006866 S/2560/63/qOO/015/0101,1.010rl.I ~AUTHOR: Keirim~-Mark~s, 1.

Local shielding is designed taldng into account the varying radios ensitivity of different body organs and the considerable unevenness of the radiation field inside the spacecraft cabin. Calculation of local shielding is based on determination of the effectiveness of shielding of an organ by parts of the ship and by other parts of the Pody. A model of a so-called standard.man (with typical. Card L lo959-67 ACC NR: A! placement of organs) was used to facilitate dose calculations for individual vital organs. Spatial distributions of tissue thicImesses with respect to the vital organs were determined using this model. On the basis of data obtained, calculations were made of doses from a solar flare for various critical organs, assuming a hypothetical spacecraft hull. Calculations utiUzed dependences of dose on tissue depth for given shielding thicImesbuo. Results of these calculations show the definite possibility of weight economy with the use of local shielding. [W.A.

TITLE: Rectification of metals PERIODICAL: Zhurnal priklndnoy khimii, v. 36, no. 1, 1963, 56 - 62 TEXT: The-rectification of Hg (at atm. pressure and under vacuum) and of Cd and Zn (vocuum only) was atixdied in an effort to develop a suitable apparntus for this purpose and to assess the possibilities of this method for the produc- tion of very pure metals. A transparent silica column of 18 bubbler-type plates was used for Hg. The apparatus is shown in Fig. 1.. Both this, and a similar 10-pl-tte column allowed suf:cessful rectification to be cnrried out; the collecting rates varied. e.g. from 3.7 to 28.0 g distilled Hg per minute. Regulation of the amount of reflux was difficult. Apparatus of basically the same construction was used for Cd and Za, with a 10-plate column, with equally successful')results. It is concluded Card 1/4 S/080/63/036/001/005/026 Rectification of metals D226/D307 that for columns up to 80 mm in dia, the plate separation, 5, is sufficient when S = (3 + 5) h [6ic*] where h is the thickness of metal on each plate. Changes in the linear velocity of the vapor along the column are calculated and found to increase from 1.44 at plate 1 to 11.4 m/sec on rAnte 9. The velocity increased sharply from plate to plate, tbo increments becoming greater towards the top of the column. bubbling on the plates is an essential though not the only condition for successful purification on,columne of this type.

Such columns are fabricated from 90-150 mm thick forged steel by electro- slag welding. The 25Kh3NM steel contains up to 2% nickel, and the required hardening with subsequent high tempering to sorbite is not possible at most Soviet plants. The 17Kh3GMFA steel is nickelfree, has a low cooper content, and is easier to weld because of its low carbon content.

The cooling technique after normalization and high tempering corresponds to the recomendations of TsNIITmash. Conclusions: (1) The recommended technique (Kh5M wire, AN-8 flux, 50-55% of base metal in the weld metal) ensures sound welded joints without flaws. (2) The weld metal and the heat-affected metal at the welds in the as-welded state have an acicular tmostite structure with a hardness of 380-400HV. Therefore,high tempering or annealing must be used directly after welding, before the metal cools-down completely, and this must be done regardless of the final heat treatment. (3) After normalization and tempering, the strength, plasticity and toughness of the weld metal and heat-affected zone fully meet the technical requirements. (4) The weld metal has no tendency to hot embrittlement in long holding at up to 3700C. (5) Normalization and high tempering ensure a sufficiently uniform metal structure in welded joints, and this in combination with high Cr content in the weld and base metal seems to result in a high Card 3/4 Electro-slag welding ... resistance to hydrogen corrosion. test for hydrogen corrosion.

The weld-affected zone within 1. 5-2 mm from the metal-fusion border in welds between 2OKh3MVF 240-mm-thick plate and 30GKh2MF 285-mm--thick plate was investigated. It was found that a single'- time thermal treatment at 930C. i. a. , higher by 40C than the critical point Ac., COM 1/2 ACCESSION NR: AP4029255 did not produce any substantial change in the overheated zone of 20Kh3MVF. A double thermal treatment, at 930 and 980C, resulted in much better toughness in both steels; this treatment is recommended for electroslag-%ielded parts made from the above steels.

During the process of manufacture of cold rolled or drawn tubes made of austenitia and ferritic steels, difficulties arise which are due to changes in the structure and properties of the metal and which are not always-fully explained. For elucidating the nature of some of these changes, investigations were carried out which are described in this paper. The chemical compositions of the investipted steels were as follows: Steel Kh25T; 0.1510o C; 0.9% Si; 0.77% Mn; 26.7% Cr; 0.1+% Ni; 0.73% Ti. Steel MlMTS 0.11% C; 0.62% Si; 0.17% Mn; 17% Cr; 8.7% Ni; 0.64% Ti.

After hot rolling the tubes were quenched in water from 1100 and 950 OC respectively. Following that, the tubes were cold rolled or cold drawn with maximum degrees of deformation so as to obtain clearly pronounced textures. The reductions were 75% for the steel IKhl8N9T and 95% for the steel Kh25T. From the tubes 20 x 20 mm specimens were-cut which were heated to 400, 5oo, 6oo, 700 and 800 OC and held at each temperature for durations of 1, 5~ 25, 50 and 1.00 hours. The structural transformations were studied by hardness measurements, microstructure study with an optical microscope, static metallography and X-ray structural anal7sis,. The results of the changes in hardness and stretching of the grains in cold drawn and cold rolled tubes from the two steels are entered in Figs 1 and 2, and 3 and )+, respectively. The results show that quenched and cold worked austenite of the steel lKhl8N9T is more inclined to develop phase transformations leading to an increase in hardness than annealed and cold deformed austenite which is characterised by a greater stability. Card 2/4 81879 8/129/60/000/08/006/009 E073/El35 Changes in the Structure of Cold Worked Steels lKhl8N9T and Kh25T during Heating Although the general relations remain the same, comparison of the graphs in Figs 39 4 with those in Figs 1, 2, lead to the conclusion that In the steel Kh25T the transformations are considerably slower than in the steel lKhl8N9T. It is possible that this is due not only to the differing nature of the forming phases, but also to a generally lower level of type II distortions in the ferritic steel than in the more strongly work-hardened austenitic steel. The experimentally established martensitic transformation in the steel lKhl8N9T and the formation of a a phase in the steel Kh25T during repeated heating of cold worked specimens lead to a further conclusion relating to the influence of the accumulated deformation energy on the distribution of the individual elements in the solid solution. The determined transformations in both these steels could not occur in the equilibrium state. Such occurrence is made possible in the temperature range 44D0-600 OC by a redistribution of the elements which leads to a lowering of the solid solution and formation of Card 3/1r Changes in the Structure of Cold Kh25'T during Heating 81879 8/129/60/000/08/006/009 E073/E135 Worked Steels lKhl8NqT and islands which are poor in nickel. Apparently such lowering leads In many cases to the formation of thermodynamically more stable alloys. There are 5 figures. ASSOCIATIONS.
